What are your difficulties? These "circuit" from standard datasheets in .pdf files:
http://alldatasheet.com/
http://www.datasheetcatalog.com/
The guys came to Russian free energy forums without knowledge in the development of electronic devices. I told on the forums  what and how to do.
They did what they had the mind for.
Very good forum on circuitry of high-voltage converters, Tesla coils, X-ray, HF-microwave, i got a lot of knowledge there:

but not everyone is allowed to go, it is difficult to register for beginners.
And on that forum do not like the inventors of perpetual motion machines.

Nick,

the kacher will not be controllable in frequency, it will oscillate on its predetermined self-oscillation frequency.
What controllable is is: the moment of activating the kacher, the duration of such an activation, the position compared to the push pull (sine) wave and the number of those pulses.

Look at this Stalker video from about minute 14, you will see the pulses being created by his circuit.

User Sergh seems very knowledgeable in both electronics and Russian, so he might be able to explain the specifics mentioned in that Stalker video.

I don't want to keep stating the obvious but you don't need to ask Serge you can do it your self 'Google', use google youtube
click cc then translate to English then step through the video read subtitle on the screen and make notes! simple.
Asking others you lose in the translation as it gets truncated, any way your choice.

Any way you really need to under stand what's going on in stalkers video's before you lose them, it's time consuming, but you need to get your head round it.

PS note The Stalker down load site, I had a look at it, and ended up with it knocking out my virus protection software and having to erase spy ware, be aware.

Happy days

   T-1000: Can you tell me what's up with Geo's Kacher circuit? As he has not been posting lately.
   Does his Kacher have duty and frequency controls, or not?

The katcher is self-resonant with Tesla coil and there are no frequency/duty cycle controls. The main addition to that is the interrupter which abruptly shuts down katcher when powering off signal is on input.

If you are looking for duty cycle and frequency controls it is driver not katcher. I had a lot time spent with that but finding difficult to get best output from Tesla coil when it does not match on the frequency given from driver.

Cheers!

Since this a thread to post Kapanadze power devices I am posting as to what Wesley had said about Adrian from Moldova, I hope that this is not true until it is official..

His You Tube channel has many videos that he made to show how and why these devices are very simple to make and the theory that goes from him. They are in Russian...however..

 “ All my friends who are working on alternative energy. The essence of the invention: this device is capable of collecting atmospheric charge and convert it into useful electricity without ignoring neither gas nor coal, this is a new and pure source of energy, because of the atmosphere of this giganous energy storage device and the energy that manifests itself in the form of lightning, we can collect atmospheric electricity, as we know from the school physics course in clear weather with every meter from the ground the potential grows by 150 volts! And during the rain or snowfall as much as 300v per square meter. The current strength in the atmosphere of the earth reaches 10-500 thousand amperes, the voltage - from tens of millions to one billion volts of this energy is enough for every person in the world. The device has four parts, the first one is a high voltage source for exciting electrons around the resonator, the second part is the capacitor which will accumulate the charge, the third part of the lowering transformer from 10kV to 220. The high voltage source TDKS charges the capacitor while charging the potential on the condenser and the resonator increases to the maximum value, thereby electrating the entire atmospheric charge, then a breakdown takes place at the discharger and all the current passes through the lowering transformation Thus, it draws the whole potential from the resonator (antennas) with which all atmospheric electricity enters the system, and the process continues to repeat again.
 
What is the letter and phase here? If the video shows an overview of an unprepared generator? It was rotated on the spot because it showed the side of the socket, one hand holds the video camera and the other turns a box that weighs more than 5 pounds ......
 And what do you think in the illegal generator? While the demonstration did not work yet ready for the excitation of the resonator, but the principle has long been known and many people have repeated it and did, I have been telling people how it all works for many years, but no one takes into account everyone believes in the zero point and the energy from the ether is therefore nothing with their own hands They can not do everything but people just do not want to think. I lay out on the video channel just to interest people and show their achievements, but mostly found among the degraded proletariat of smart people who have a head and who they are able to do. Basically, those who had a head but made a mistake and wanted to give these technologies to all people, then from their own whining ended their lives very sad .......”

a Re-post from Russian…by Acca…

Hi Acca,
Personally I think this device of him can it really work! Because if it is false then he is not dead !!!
 
But ferrite material in the old TV of the Russian, now the ferrite type of replacement I do not know! . .

Some time ago  I was told to put some of Adrian Guska videos out of line due to pressure  on him. That was the time when I spoke to him and he was terribly scared
In next session he told me details  about Russians  in the room  telling him what to say to me.
And today I make it public again

ok, i watched the video at your request. Stalker tiresily talks about the usual circuit. From this I want to sleep.
The circuit can be normal described by text on one page. But he needs youtube.

I did not see the main oscillogram that I expected during the video clip.
He often observed in resonant devices.

I guess that the Stalker did not get to the power section tests, or the transistors burned out on first time. It was necessary to make a bridge or a half-bridge, and he made a push-pull.  Or his Tesla worked very poorly.

Wesley, here is about 368,000 high power free energy generators:

https://www.youtube.com/results?search_query=high+power+free+energy+generator

Do you personally have at least one?

Sergh 368000 really oh so many, Just a bit of advice If I were you I wouldn't bother quiting your day day time job just yet
with a view replicating any of them for a living. 

Wesley
Thanks for re'posting the video's i'm sure we will enjoy re watching them

Sergh,

thanks for your effort to view the Stalker video.
so its not me alone who starts falling asleep when viewing   

On the other hand, i doubt that you understand the total purpose of the shown diagram, or its me who does not understand your comment above about:
"It was necessary to make a bridge or a half-bridge, and he made a push-pull."

 
The push pull (not a bridge or a half-bridge) is needed to drive the yoke and has nothing to do with the kacher part other then syncing with each other.

Thanks also for the link to http://flyback.org.ru  as it has lots of info (and as usual comments).

Itsu
